with Tableau one can visualize routes on a map (e.g. product transport) using the path feature. Unfortunately there is no option to assing a shape (arrow) to these lines. As a one workaround one can use the e.g. the path ID on the size of the line to get shaped lines (see attached JPG). But the message would be way clearer and less confusing if it was possible to have "real" arrows build in in Tableau, similar to the existing path feature.
=> Please add arrows on maps as a feature
